TRZST / TRZSP series electromagnetic rotation speed sensor is a universal speed sensor with high cost performance and wide application. The inner part is composed of magnetic steel, soft magnetic armature and coil.

The magnetic field (line of force) is sent out by the magnet. Through the armature and the coil, an AC voltage signal will be induced inside the coil. Let the sensor close to the speed measuring gear on the rotating shaft to sense the frequency signal proportional to the rotating speed; if it is an involute gear, the induced voltage is a sine wave, the signal amplitude is proportional to the rotating speed, and is inversely proportional to the gap between the probe end face and the tooth top.

TRZST/TRZSP series electromagnetic rotation speed sensor has the characteristics of simple structure, good rigidity, good environmental resistance, not affected by vibration, temperature, oil and dust, and is widely used.

TRZST/TRZSP series electromagnetic rotation speed sensors are available in low resistance and high resistance versions, medium and high temperature versions and explosion-proof design to meet different measurement requirements.
